Love mine, too! At first I thought a DS Leica would be slower, but learned that you can actually advance faster with two short strokes, and frequently do so with my M6 and M4-2.

So to answer the OP's question: If you don't need a built-in meter and prefer the 50 and 90 lenses, the M3 is your camera. If you like the 35 lens, go for the M2. If you want a meter, the M6 is great, especially with the MP viewfinder modification.
